Acoustic correction for playing music with a laptop

MathAudio Room EQ version 3.02 was released on December 21, 2025 and can still be used for free with foobar2000. In theory, it can be used with a simple laptop connected to active speakers via the headphone output. The extensive description of this plugin is encouraging.

Corrects deficiencies of room acoustics (multipoint compensation).
Corrects acoustic imperfections of speakers.
Avoids the pre-echo (pre-ringing) problem of conventional convolver-based room correction systems. The absence of pre-echo ensures the neutrality of the sound.
Works in rooms, halls and outdoor venues of any size.
Performs frequency response correction, phase response correction and time domain correction.
Quells resonance peaks of frequency response while leaving the deep notches. Avoids the overcompensation which happens in conventional linearizing room correction systems.
Manually adjustable level of compensation allows one to reach the maximum transparency of the sound.
Supports full range of sample rates from 44,056 kHz up to 384 kHz. All sample rates are supported without resampling to avoid any possible loss in quality.
Includes a custom target curve feature.
Applies 64-bit signal path throughout.
Works with USB measurement microphones (e.g. MiniDSP UMIK-1 or Dayton Audio UMM-6) or standard measurement microphones (e.g. NADY CM100 or Dayton Audio EMM-6).
Supports microphone calibration files.
Applies a patented method of frequency response correction.
Works as a simple conventional mouse drawing EQ if necessary.
Supports automatic scaling for 4k monitors.
Supports manual window resizing (drag the bottom right corner of the window).
Works as a conventional mouse drawing EQ if necessary: load a new instance of Room EQ, select the "Room EQ" radio button, move the cursor of your mouse to one of the frequency response windows, press the left button of the mouse and draw your own frequency response.

This is not so promising in practice, but when it works, playing music even with simple speakers becomes more enjoyable. The comparison was made with Logitech speakers with a passive membrane, and the reference program was AIMP.

 

A very real challenge when making adjustments with a laptop can be connecting a standard microphone. Modern models have integrated headphone and microphone jacks.
